When the network is abnormal in the working environment, the detection is that a server sends data packets abnormally. Using the netstat command to check, it is found that the process state of IptabLex is an abnormal connection. Can not effectively clear, so want to know which directory of this program is in a dead state.

[root@edu-web1 /] # netstat-anp | less

The status of the process in the event of a problem is:

[root@edu-web1 /] ps x

The way to find the startup path of a process is:

1. We can get the PID of the zombie process from the ps command, as in 23347 in the example above

two。 Go to the directory named after the PID under the / proc directory

3. Enter ls-ail, and the exe link in the result corresponds to the full path details of the executable file.

[root@edu-web1 /] ls / proc/ found folder 23347

[root@edu-web1 /] cd / proc/23347 [root@edu-web1 23347] ls-ail

You can find that there is an exception in this connection, and the corresponding application also has problems. The rest is to find a way to delete the corresponding application of this zombie process, which is usually redundant or junk, but rm-f can kill it.

Summary

The above is the linux introduced by the editor to find the full path of the startup program according to the process number PID. I hope it will be helpful to you.
